Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105856, here are decompositions:

89 + 105767 = 105856
173 + 105683 = 105856
293 + 105563 = 105856
347 + 105509 = 105856
353 + 105503 = 105856
389 + 105467 = 105856
419 + 105437 = 105856
449 + 105407 = 105856

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 105.856 and was likely granted around 1870.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
